LOUIS BULAsKY, or NEW YORK, N. Y.

WORK GUIDE OR GAGE FOR SEWING-MACHINES.

To all whom it may concern:

Be it known that I, LoUIs BULASKY, a citizen of the United States,residing in the borough of Manhattan of the city of New York, in theState of New York, have invented a new and Improved \Vork Guide or Gagefor Sewing-lVIachines, of which the following is a specification,reference being had to the accompanying drawings, forming a part hereof.

This invention has for its object to produce an improved work guide orgage, especially applicable to machines for stitching wire to the edgeof buckram hat frames and felt hats, but also applicable to otherpurposes, which shall hold the wire in proper relation to the hat frameor brim, shall be readily attachable for different classes of work, as,for example, when the stitches are to pass across the wire or are toengage the fabric casing of the wire, and shall be so eonstructed as todiminish the danger of breakage of the needle in work of this character.

The invention will be more fully explained hereinafter with reference tothe ac companying drawings in which it is illustrated and 1n Wl11Cl1--Figure l is a view in front elevation of a portion of a sewing machineillustrating the application of the improved guide or gage to the worktable and its relation to the needle and presser foot. Fig. 2 is a topview of the guide or gage. Fig. 3 is an underside view thereof. Fig. 1is a detail view in section on the plane indicated by the line 4-it ofFig. 2, looking in the direction of the arrow. Fig. 5 is a top view,partly in horizontal section. Fig. 6 is an underside view, similar toFig. 3, but showing some of the parts in different posit-ions. Figs. 7,8 and 9 are detail views illustrating different modes of stitching wireon the edge of buckram hat frames and felt hats.

In Fig. 1 of the drawings, the improved guide or gage is shown asapplied to the work table a in proper relation to the needle 0 which, inmachines adapted for the particular kind of work referred to above, hasnot only a movement of vertical reciprocation but may have also amovement of lateral reciprocation for the forn'iation of zigzagstitches, and the improved gage or gulde is designed with especialreference to the requirements of such a machine. It is so constructed asto be adapted for the dif Specification of Letters Patent.

fereut kinds of work which are ordinarily done on machines of thischaracter, such as the sewing of paper or cotton covered wire upon thesurface of buckram hat frames, near the edge, in which case the threadenters the material of the hat at each side of the wire, crossingto-and-fro over the wire, as shown in Fig. 7; or in sewing silk coveredwire against the edge of felt hats, in which case the sewing threadfirst enters the material of the hat and then catches the covering ofthe wire adjacent to the edge of the hat, as shown in Fig. 8; or insewing paper or cotton covered wire against the edge of felt hats, to beafterward bound over, in which case the sewing thread first enters thematerial of the hat and then passes outside of the wire, as shown inFig. 9; and also so as to be adapted for wires of different thicknesses.The gage or guide comprises a supporting plate 0 which is suitablyshaped and adapted to be secured adj ustably to the base of the machine,having a longitudinal slot 0 fitting upon a shorter rectangularprojection 0 of the base of the machine and held thereon by a thumbscrew 0.

Pivoted upon the plate 0, as at p, is a plate or lever 72 which at itsleft hand end is bent to form a guide 72 as shown most clearly in Figs.1 and 5, for the edge of the hat or frame, and a thin finger p to lieunder the edge of the hat or frame to prevent it from working under theguide [2 This guide also holds the wire from moving 'to the left and isnot adjustable except as it is adjustable with the supporting plate 0. Aspring p (see Figs. 1 and 5) cooperates with the plate 01' lever 72 tohold it in its working position, as shown in full lines in Fig. 1, butthe plate or lever may be tilted into the position indicated by dottedlines in Fig. 1, to permit the release of the work at any time withoutrequiring the cutting of the thread or the wire.

Mounted to slide on the supportim plate 0 are two outside guides Q andr. T 10 outside guide 9 is formed with a depending guide lip q adaptedto rest against the outer side of the wire, that is, against that sidewhich is the enter with respect to the body of the hat, and to hold itagainst the body of the hat and prevent it from being pushed away by theneedle or otherwise. To accommodate wires of different thicknesses theplate 9 is adjustable, being formed with an elongated slot Q2 'toreceive a screw stud 9 which is fixed in the plate 0, and being held inadjusted position by a thumb nut g on the stud The rear guide '1 isoperative when the wire is to be stitched against the edge of the hatbrim and is arranged to be held in an inoperative position when the wireis to be stitched upon the brim, as shown in Fig. 7. The rear guide 9"is also formed with a depending guide lip r at its left "hand end andhas a limited sliding movement on the support-ing plate 0, being formedwith an elongated slot 7 to receive a holding and guide screw W A springr which is coiled and slipped upon pin 29 with one end bearing againstthe fixed abutment, and the other end extending through a slot in thesupporting plate 0 as shown in Fig. 3 and entering a hole formed in therear guide 1" and bearing against the side of the hole acts upon therear guide 1' to press it normally to the left, but permits the guide toyield to the right in a horizontal plane away from the needle, after itspoint has entered the cover of the wire, and its thicker portion thruststhe wire farther to the right, thus preventing the bending of the needleand the throwing of the needle out of proper alinement with respect tothe looper. This yielding, rear guide, is operative when the machine isused upon such work as is indicated in Fig. 8, but when the needlepasses alternately on opposite sides of the wire, as in the character ofwork indicated in Figs. 7 and 9, then the rear guide must be drawn andheld back out of the way so as to permit the needle to descend at theright hand side of "the wire as well as at the left hand side of thewire. A latch s, properly formed to engage the guide plate 1, is pivotedon the supporting plate 0 to hold the guide in its right hand orinoperative position. A lug r on the rear guide 1' is adapted to engagethe front guide 9 so as to limit the forward movement of the guide 1'with respect to the guide 9, so that the guide lip 1" cannot standfarther to the left than the guide lip no matter what the adjustedposition of the guide 9 may be.

In Figs. 5 and 6 of the drawings the two guides are shown as havingtheir lips q and 1" in line and as adapted for such work as is indicatedin F ig. 8, the rear guide being released by the latch s and the lug 7'standing in contact with the rear end of the guide 9. In these figures,the adjustment of the two guides together, to accommodate wires ofdifferent diameters, is indicated by dotted lines. It will be seen thatthe rear guide 1* is free to yield to the right to prevent bending orbreaking of the needle. In Figs. 2 and 3, the rear guide 1" is shown asengaged by the latch s to hold it out of the way of the needle so thatthe stitches can be carried entirely across the wire.

evens It will be understood that various changes in details ofconstructlon and arrangement can be made Without departing from thesupporting plate and located immediately to the rear of said front guidewith reference to the direction of travel of the material operated upon,said rear guide being disposed to one side of or laterally of the pathof travel of the needle and the said rear guide being yieldable in adirection transverse to the path of travel of the material operatedupon; whereby lateral thrust resulting from contact of the needle withan unyielding part of the work operated upon will be transmitted to andwill cause said rear guide to yield in the manner aforesaid.

2. A work gage for sewing machines comprising a work supporting plateadapted to be secured to the base of the machine, a front work guidemounted on the supporting plate with its end close to the machine base,a rear work guide mounted on the supporting plate with its end close tothe machine base and in line laterally with the needle, said guide beingmounted movably toward and away from the needle in a horizontal planeindependently of the front guide, a spring to press the rear guideyie1dingly toward the needle whereby the guide may yield laterally asthe thicker portion of the needle passes through the work adjacent tothe base plate and a latch independent of said rear guide but adapted toengage the same to hold it away from the work.

3. In a sewing machine, the combination of a work supporting plate, afront outside work guide mounted on the supporting plate, and a rearoutside work guide mounted yieldingly in a horizontal plane from theneedle, said rear guide being adapted to engage the front guide, wherebythe rear guide is adjusted with the front guide and may yieldindependently thereof.

4. In a sewing machine, the combination of a work supporting plate, anoutside Work guide mounted adjustably on the support ing plate, and aspring pressed plate lever pivoted on the supporting plate above thework guide and having a lip to rest under the fabric and form a guide fr he g o the material.
